Fish Diversity of Estuaries Revealed by Environmental DNA

  • Chapter
  • First Online:
Fish Diversity of Japan

Abstract

Estuarine ecosystems are important habitats for many fish species. Large-scale patterns of estuarine fish communities can be affected by geographical factors, such as water temperature and latitude, which either limit or allow fish dispersal, and/or by environmental factors that select locally adapted species. Furthermore, increased human activity has also altered fish diversity through the modification of estuarine environments. In this study, we used environmental DNA metabarcoding to study a large-scale pattern of estuarine fish communities across 26 watersheds in the Japanese Archipelago, and assessed the effects of geographical, environmental, and anthropogenic factors in structuring these communities. Of the 197 fish species detected, 40 species were red-listed by the Japanese Ministry of Environment and seven were alien. Non-metric multidimensional scaling showed that both latitude and water temperature affected river mouth fish communities. Although other anthropogenic factors were not found to affect these communities, the bank artificialization rate was influenced. Furthermore, the relationship between the fish community and ocean currents was weak. The number of red-listed fish affected fish community structures, whereas that of alien species did not. The numbers of red-listed fish were negatively correlated with the bank artificialization rate and the rate of tetrapod formation. These findings provide useful information that may be used to conserve estuarine ecosystems.
